The present invention relates to a numerical map renewal system via the global positioning system (GPS) coordinate synthesis for a control point of a reflection image and, more specifically, to a numerical map renewal system via the GPS coordinate synthesis for a control point of a reflection image, which is capable of outputting map images similar to a present image of a region by editing the map image outputted on a navigation in accordance with natural or artificial changes on a specific region. In addition, the system can also reflect the changes of coastline onto the map image in real time by checking a difference in ebb and flow of the tide, and the reflection of the changes in coastline during a rainy or dry season is possible on the map by enlarging the reflection of the change. Accordingly, as the location of the coastline by the ebb and flow of the tide shown on the map image is directly reflected and outputted on the navigation when a user passes by a road nearby the coastline, the user can easily grasp and determine the geographical features on which the user is passing by. |
